Definitions

  • the invention relates to the mounting of a shaft of a bevel gear.
  • a bearing of a shaft of a machine element in particular a pinion shaft of a transmission in a bore for passage of the shaft having housing by means of a double-row preloaded roller bearing whose outer ring is provided with a radially outwardly directed flange known.
  • An object of the invention is to provide an improved bearing a shaft of a bevel gear so that a variety of components of the storage is used unchanged for different applications.
  • the bevel gear nearest rolling bearing with a second rolling bearing, and with an integrally formed, hollow cylinder-like Outer part, the outer part designed as an outer raceway for rolling elements of the second rolling bearing and in the outer part of a separate outer ring used as an outer raceway for rolling elements of the first rolling bearing.
  • the invention is based on the recognition that when storing a shaft of a bevel gear, in particular the bevel gear side roller bearing adapted to the particular application differently interpreted and dimensioned. Due to the fact that this rolling bearing is designed according to claim 1 with a separate outer ring, the design adapted to the particular application is carried out by appropriate dimensioning of the first rolling bearing, wherein only an outer diameter whose outer ring remains the same regardless of the application. For different applications, different bearing types with the same bearing outer ring diameter are therefore used for the first rolling bearing. Furthermore, however, in particular the outer part and also other components of the storage for different applications remain under-changed, which advantageously brings with it a simple and inexpensive manufacturability by thus achievable high volumes. Thus, the storage concept according to claim 1 is particularly suitable for the economical production of comparable, but nevertheless different series of smaller quantities.
  • the two inner rings of the two rolling bearings are designed for abutment against each other. This advantageously eliminates the need for a sleeve to be arranged therebetween, wherein a predeterminable preload for the roller bearings during assembly is ensured by a corresponding pairing of the two inner rings.
  • the shaft between the bevel gear and the first roller bearing comprises a flange, radially outwardly extending projection, which is formed integrally with the shaft, for example.
  • a gear manufacturer can mount different bevel pinions, but it is also possible with advantage for the bearing manufacturer, the shaft with the rolling bearings mounted on it to deliver that the bearings are already mounted with correct employment and thus with an accurate adjustment of the preload force.
  • the bearing manufacturer is usually better acquainted with the employment of the bearing than, for example, the gearbox mounting manufacturer, which advantageously avoids problems with the gearbox manufacturer.
  • the figure shows as an embodiment of the invention a longitudinal section through a bearing of a shaft 10 of a bevel pinion 5, wherein the bevel pinion 5, the shaft 10 and a shaft nut 18 are shown uncut.
  • the integrally formed shaft 10 comprises in the left area a cylindrical portion 12 on which the bevel pinion 5 can be fastened.
  • an inner ring 22 of a first designed as a tapered roller bearing roller bearing.
  • an outer ring 24 of the first rolling bearing is arranged in a corresponding recess of an outer part 42.
  • the frustoconical rolling elements 28 of the first rolling bearing are arranged.
  • the outer part 42 comprises a flange-like projection with holes through which the outer part 42 can be screwed to a transmission housing. Furthermore, the outer part 42 forms the outer raceway for rolling elements 38 of a second, designed for example as angular contact ball bearings. Similar to the first roller bearing and the second roller bearing comprises an inner ring 32, wherein the inner rings 22 and 32 of the two rolling bearings are arranged on a further cylindrical portion 16 of the shaft 10.
  • a further flange portion 48 is disposed on the latter cylinder-like portion 16 of the shaft 10, wherein the flange portion 48, the two inner rings 22 and 32 and the sleeve 46 are secured by the screwed onto the shaft 10 shaft nut 18 on the shaft 10 and a tightening torque the shaft nut 18, the bias of the bearings is adjustable.
  • a sealing ring 44 is arranged between the outer part 42 and the flange part 48.
  • the outer part 42 is formed with a corresponding seat for the sealing ring 44.
  • the sealing ring 44 is formed, for example, as a radial shaft seal, on the intended purpose not intended for turning outer part 42 is fixed and lies with its sealing lip sealingly on the flange 48 at.
  • the sealing ring can also rest on the shaft or the inner ring sealingly.
  • the sleeve 46 may also be omitted, so that correspondingly formed inner rings abut the front side directly against each other. It is ensured by a corresponding Zucruen the two inner rings to each other a predetermined preload for the bearings during their assembly with advantage.
  • the disc-like portion 14 and / or the further flange portion 48 is omitted and / or the bevel pinion is formed integrally with the shaft.
  • the inner rings can be mounted on the shaft in other ways than by the shaft nut 18th
